the alloy A-286 boasts extremely high yield strength and creep-rupture strength as well as great fabrication characteristics and weldability.The Incoloy A-286 nickel alloy is an iron-nickel-chromium alloy with additions of molybdenum, titanium, aluminum, vanadium and trace amount of boron that stiffen the alloy matrix, thus providing high mechanical strength. At the temperature under 650℃.
These superior prosperities of this high temperature alloy make it useful for high temperature bearing components of aircraft engine, such as turbine disc, compressor disc, rotor blade and fastener.
